I have a RCA L46WD22YX5 and the sound went out. I get some buzzing at full volume that resembles the music that should be playing. I have checked all settings (i.e. closed captioning, mute, internal speakers on/off), and there is nothing on any of the outputs. (ex. headphone jack, red/white audio).
